NASA reports data from Rosetta Orbiter show origin of Earth’s water not from comets like Comet 67P/Churyumov-Gerasimenko

NASA - National Aeronautics and Space AdministrationPasadena, CA – The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids.

Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko. The findings were published today in the journal Science.

NASA’s Spitzer, Hubble and Herschel Space Telescopes observes Warm Gases stopping Galaxy from making new Stars

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – Some like it hot, but for creating new stars, a cool cosmic environment is ideal. As a new study suggests, a surge of warm gas into a nearby galaxy — left over from the devouring of a separate galaxy — has extinguished star formation by agitating the available chilled gas.

The unique findings illustrate a new dimension to galaxy evolution, and come courtesy of the European Space Agency’s Herschel space observatory, in which NASA played a key role, and NASA’s Spitzer and Hubble space telescopes.

NASA’s Mars Curiosity Rover discovers sediment deposits in Martian Lake Bed

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Observations by NASA’s Curiosity Rover indicate Mars’ Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.

This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet.

“If our hypothesis for Mount Sharp holds up, it challenges the notion that warm and wet conditions were transient, local, or only underground on Mars,” said Ashwin Vasavada, Curiosity deputy project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “A more radical explanation is that Mars’ ancient, thicker atmosphere raised temperatures above freezing globally, but so far we don’t know how the atmosphere did that.”

NASA’s New Horizons Spacecraft arrives at Pluto

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After a voyage of nearly nine years and three billion miles —the farthest any space mission has ever traveled to reach its primary target – NASA’s New Horizons spacecraft came out of hibernation on December 6th for its long-awaited 2015 encounter with the Pluto system.

Operators at the Johns Hopkins University Applied Physics Laboratory in Laurel, MD, confirmed at 9:53pm (EST) that New Horizons, operating on pre-programmed computer commands, had switched from hibernation to “active” mode. Moving at light speed, the radio signal from New Horizons – currently more than 2.9 billion miles from Earth, and just over 162 million miles from Pluto – needed four hours and 26 minutes to reach NASA’s Deep Space Network station in Canberra, Australia.

NASA’s Dawn spacecraft captures new image of Dwarf Planet Ceres

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Dawn spacecraft has delivered a glimpse of Ceres, the largest body in the main asteroid belt, in a new image taken 740,000 miles (1.2 million kilometers) from the dwarf planet. This is Dawn’s best image yet of Ceres as the spacecraft makes its way toward this unexplored world.

“Now, finally, we have a spacecraft on the verge of unveiling this mysterious, alien world. Soon it will reveal myriad secrets Ceres has held since the dawn of the solar system,” said Marc Rayman, of NASA’s Jet Propulsion Laboratory in Pasadena, California, chief engineer and mission director of the Dawn mission.

From about three times the distance from Earth to the moon, NASA's Dawn spacecraft spies its final destination -- the dwarf planet Ceres. This uncropped, unmagnified view of Ceres was taken by Dawn on Dec. 1, 2014. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA working with other space agencies to explore Comets, Asteroids and other Celestial Bodies

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA and space agencies across the globe are opening up new possibilities for space exploration with missions to comets, asteroids, and other celestial bodies.

Following NASA, European Space Agency (ESA), and Indian Space Research Organisation (ISRO) spacecraft observations of the close flyby of Mars by comet Siding Spring in October, and the successful November landing of ESA’s Philae lander on comet 67P/Churyumov–Gerasimenko, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission on December 3rd to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth.

NASA’s Orion Spacecraft travels to 3,600 miles above Earth completing First Spaceflight Test

 

Written by Michael Curie
NASA’s Kennedy Space Center, FL

NASA - National Aeronautics and Space AdministrationCape Canaveral, FL – NASA marked a major milestone Friday on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years.

“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars,” said NASA Administrator Charles Bolden. “The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”

Following a perfect launch and more than four hours in Earth's orbit, NASA's Orion spacecraft is seen from an unpiloted aircraft descending under three massive red and white main parachutes and then shortly after its bullseye splashdown in the Pacific Ocean, 600 miles southwest of San Diego. During the uncrewed test, Orion traveled twice through the Van Allen belt, where it experienced periods of intense radiation, and reached an altitude of 3,600 miles above Earth. The spacecraft hit speeds of 20,000 mph and weathered temperatures approaching 4,000 degrees Fahrenheit as it entered Earth’s atmosphere. (NASA)

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On December 3rd, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth.

NASA and JAXA are cooperating on the science of the mission and NASA will receive a portion of the Hayabusa2 sample in exchange for providing Deep Space Network communications and navigation support for the mission.

NASA’s Orion Spacecraft launch moved to Friday, December 5th

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Orion’s managers for NASA, Lockheed Martin and the United Launch Alliance said they will push on with planning to launch Orion on its flight test Friday morning at 7:05am EST. The launch window will be 2 hours, 39 minutes, the same time span as Thursday. “Our plan is to fly tomorrow,” said Mark Geyer, Orion program manager.

Fill-and-drain valves on the Delta IV Heavy will be tested throughout the day so the launch team can prevent a mechanical problem like one that came up Thursday. “We’re very confident we’re going to be able to exonerate the equipment,” said Dan Collins, chief operating officer of United Launch Alliance.

NASA uses Keck Observatory telescopes to determine dust will likely not to block images of star’s Planets

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Planet hunters received some good news recently. A new study concluded that, on average, sun-like stars aren’t all that dusty. Less dust means better odds of snapping clear pictures of the stars’ planets in the future.

These results come from surveying nearly 50 stars from 2008 to 2011 using the Keck Interferometer, a former NASA key science project that combined the power of the twin W. M. Keck Observatory telescopes atop Mauna Kea, Hawaii.
